Megan Fox: I'm More in Love with Brian Austin Green Than Ever

She just got engaged – again – but Megan Fox says nothing is really different the second time around.

"We're just even more committed to each other than we always have been," the actress, 24, told PEOPLE about fiancé Brian Austin Green, 36, at the premiere of her new film, Jonah Hex, Thursday in Hollywood. "I'm more in love with him now than I was in the beginning."

But the couple's latest news in their six-year relationship, which included a November 2006 engagement that was later called off, shouldn't come as a complete shocker, she says.

"It's really not a re-engagement," she explains. "It's just the same engagement and for some reason now it's a news story."
